The quality of materials used to build your structure has a direct impact on its durability. Our team carries out construction materials testing – on site and in the laboratory – prior to project start-up. Our in-depth capabilities enable us to offer innovative solutions and to prevent the use of materials that could compromise the integrity of your construction project.
